pagekeyeddatasource

example for load with page index

1, define source

class listviewdatasource extends paging.pagekeyeddatasource<int, note> {
  noterepository noterepository;
  listviewdatasource(this.noterepository) {
    isendlist = false;
  }

  @override
  future<tuple2<list<note>, int>> loadinitial() async {
    final result = await noterepository.getnotes(0);
    return tuple2(result, 0);
  }

  @override
  future<tuple2<list<note>, int>> loadpageafter(int params) async {
    if (params == 6) isendlist = true;
    final result = await noterepository.getnotes(params + 1);
    return tuple2(result, params + 1);
  }
}

2, listview

      listview<note>(
        key: key,
        padding: edgeinsets.all(16),
        itembuilder: (context, data, child) {
          return notewidget(data);
        },
        pagedatasource: datasource,
      ),

3, gridview

      paging.gridview<note>(
        key: key,
        padding: edgeinsets.all(16),
        itembuilder: (context, data, child) {
          return notegridwidget(data);
        },
        delegate: slivergriddelegatewithfixedcrossaxiscount(
            crossaxiscount: 2,
          mainaxisspacing: 16,
          crossaxisspacing: 16
        ),
        pagedatasource: datasource,
      ),
